30-60mm Alumina 75% Grinding Ball for Grinding Machine
30-60mm Alumina 75% grinding ball used in machines
The Chemxin 75 Alumina Support Media is in chemical composition 75% alpha alumina and a maximum 0.2wt% SiO2 . Because of its high alumina content and low silica (SiO2 ), it's a very excellent and ideal product for high temperature and steam applications, such as secondary reformers in ammonia processing, where leached silica will coat downstream equipment or foul the catalyst bed.
The Chemxin 75 Alumina Support Media has very excellent thermal properties, with its high density high-temperature resistance 1550℃, also it's a good choice for heat retention or equilibration media.
For its superior chemical resistance, it's suitable for applications in olefin processes, such as ethylene dryers, where there's the polymerization problem.

2. The standard specification:
3~50mm or customized.
Advantage:
(1) High wear-resistance
The alumina balls wear-resistance is higher than the common alumina balls. When it is working, the ball won't pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.
(2) High density
The high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
